ABSTRACT 



As part of a cooperative program to restore Atlantic salmon in Maine, 

 the Fish and Wildlife Service and the Maine Sea Run Salmon Commission made 

 stream surveys to collect information on obstructions to fish, pollution, water 

 temperature, stream flow, and extent of spawning and rearing areas . 



In the Sheepscot River system it was found that 14 out of 52 tributaries 

 were seriously obstructed, and 20 had insufficient flows for salmon. Only 3 

 tributaries were considered to be of any value as salmon spawning and rearing 

 areas. In addition to a very small number of salmon, a few shad, striped bass 

 and alewives are found in the watershed. The abatement of pollution and the 

 creation of adequate flows and passages for fish migration is recommended. 



The Ducktrap River was found to have limited potentialities for salmon, 

 the most inimical feature being low stream flows. Out of 19 tributaries, 4 were 

 obstructed and 16 had flows too small for salmon. Only 2 were considered to 

 have any value for salmon spawning and rearing. Provision of adequate passage 

 facilities and the augmentation of flows is recommended.
